public class languages extends fragment { // private int current = -1; view view; context ct; sharedpreferences sp1, sp; boolean ischeck = false; string user_id, countryid; button settings; // string[] arrlanguages = new string[]{"english", "arabic"}; string[] arrlanguages = new string[] { "english", "arabic" }; string req, locale; listview lv; private locale mylocale; public languages(context c) { // todo auto-generated constructor stub this.ct = c; } /** called when activity first created. */ @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { // todo auto-generated method stub view = inflater.inflate(r.layout.languagechange, container, false); sharedpreferences sp = getactivity().getsharedpreferences("key", 0); user_id = sp.getstring("userid=", user_id); countryid = sp.getstring("countryid", countryid); settings = (button) view.findviewbyid(r.id.btnsett); lv = (listview) view.findviewbyid(android.r.id.list); lv.setadapter(new mobilearrayadapter(ct, arrlanguages)); settings.setonclicklistener(new onclicklistener() { @override public void onclick(view arg0) { // todo auto-generated method stub fragmentmanager manager = getfragmentmanager(); manager.popbackstack(); log.d("back home", "back button pressed"); } }); loadlocale(); lv.setonitemclicklistener(new onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { // selected items string selectedvalue = (string) lv.getadapter().getitem( position); toast.maketext(ct, selectedvalue, toast.length_short).show(); // setresult(result_ok, new intent().putextra("language", // arrlanguages[position])); // configuration config = new configuration(); string lang = "en"; switch (position) { case 0: lang = "en"; break; case 1: lang = "ar"; break; default: break; } changelang(lang); // getresources().updateconfiguration(config, null); lv.setitemchecked(position, true); } }); return view; } public void loadlocale() { string langpref = "language"; sharedpreferences prefs = ct.getsharedpreferences("commonprefs", activity.mode_private); string language = prefs.getstring(langpref, ""); changelang(language); } public void savelocale(string lang) { string langpref = "language"; sharedpreferences prefs = ct.getsharedpreferences("commonprefs", activity.mode_private); sharedpreferences.editor editor = prefs.edit(); editor.putstring(langpref, lang); editor.commit(); } public void changelang(string lang) { if (lang.equalsignorecase("")) return; mylocale = new locale(lang); savelocale(lang); locale.setdefault(mylocale); android.content.res.configuration config = new android.content.res.configuration(); config.locale = mylocale; ct.getresources().updateconfiguration(config, ct.getresources().getdisplaymetrics()); } class mobilearrayadapter extends arrayadapter<string> { private final context context; private final string[] values; public mobilearrayadapter(context context, string[] values) { super(context, r.layout.list_changelanguage, values); this.context = context; this.values = values; } @override public view getview(int position, view convertview, viewgroup parent) { layoutinflater inflater = (layoutinflater) context .getsystemservice(context.layout_inflater_service); view rowview = inflater.inflate(r.layout.list_changelanguage, parent, false); textview textview = (textview) rowview.findviewbyid(r.id.textview1); imageview imageview = (imageview) rowview .findviewbyid(r.id.imageview1); textview.settext(values[position]); // change icon based on name string s = values[position]; system.out.println(s); if (lv.isitemchecked(position)) { imageview.setvisibility(view.visible); ischeck = true; sharedpreferences sp = getactivity().getsharedpreferences( "check", 0); sharedpreferences.editor sedt = sp.edit(); sedt.putboolean("ischeck", ischeck = true); sedt.clear(); sedt.commit(); } else { imageview.setvisibility(view.gone); } return rowview; } } @override public void onconfigurationchanged( android.content.res.configuration newconfig) { super.onconfigurationchanged(newconfig); if (mylocale != null) { newconfig.locale = mylocale; locale.setdefault(mylocale); ct.getresources().updateconfiguration(newconfig, ct.getresources().getdisplaymetrics()); } }
try change.
lv.setonitemclicklistener(new onitemclicklistener() {
@override public void onitemclick(adapterview<?> parent, view view, int position, long id) { // selected items string selectedvalue = (string) lv.getadapter().getitem( position); toast.maketext(ct, selectedvalue, toast.length_short).show(); // setresult(result_ok, new intent().putextra("language", // arrlanguages[position])); // configuration config = new configuration(); string lang = "" + selectedvalue; changelang(lang); // getresources().updateconfiguration(config, null); lv.setitemchecked(position, true); } }); return view; }
